Reinforced Cement Concrete: Types, Advantages & Disadvantages
Disadvantages of reinforced cement concrete: The tensile strength of this concrete is 1/10 of its compressive strength. The price of this concrete used for casting is comparatively excessive. The RCC column section is larger than the metal section for multi-story construction. Due to the shrinkage, the crack increases and the strength decreases.

Fiber Reinforced Concrete Topic
Fiber-reinforced concrete (FRC) is concrete made primarily of hydraulic cements, aggregates, and discrete reinforcing fibers. Fibers suitable for reinforcing concrete have been produced from steel, glass, and organic polymers (synthetic fibers). Naturally occurring asbestos fibers and vegetable fibers, such as sisal and jute, are also used for reinforcement.
